Modern RFID system demands for low cost and low profile antennas. Microstrip antenna offers a potential solution meeting those requirements. In this paper a new antenna design using a inset fed that is suitable for high gain microstrip antennas is presented.
A compact broadband microstrip bowtie antenna is proposed. By loading properly arranged slots in a bowtie patch antenna, broadband operation of a bowtie patch antenna are presented. The maximum impedance bandwidth achieved is 27% centered around 1.8 GHz, with good pattern characteristics.
In meander line antenna the size of the dipole at given frequency is reduced by a factor that is proportional to the number of turns. The adjacent horizontal segments of the meander line antenna have opposite phase. The transmission line current neither contributes much to the radiated power nor produce losses. At the location where the current reaches maximum value at that point large amount of power...
A multiple slot microstrip patch antenna for wireless communication is presented. In this paper, inverted microstrip patch antenna, direct probe feed technique and the novel multiple shaped patch is integrated. This antenna offers low profile, wide bandwidth, high gain, and compact antenna element. The proposed multi-slotted microstrip patch antenna achieves a fractional bandwidth of 27.89% (1.82...
A novel single feed miniaturized cross patch antenna radiating at three resonant frequencies is presented. Compared to standard rectangular patches, the proposed antenna gives an area reduction of 82%, 74% and 53% for the linearly polarized radiations with center frequencies at 1.2395 GHz, 1.515 GHz, and 2.027 GHz respectively. The antenna exhibits nearly omnidirectional radiation characteristics...
In this paper, an inward scaled loop antenna (ISLA) is presented. It is created by successive scaling and rotating and fitting the scaled copies of a wideband loop antenna (WBLA) in the empty space available in it. The overall size of the antenna remains the same as that of the WBLA. The advantage of an ISLA is its improved input performance as compared to the WBLA. Impedance bandwidth of the order...
